WOW... I was just re-reading things and we look like we belong on oprah... pretty soon Jerry Springer is gonna be calling and we will be on his show throwing chairs at each other on national TV. ... if it happens, I get dibs on Springer :0

 

JERRY.........JERRY......

Enough with the bitching. If you have tpi or tbi or carb shut up.
I don't see the point of arguing. Most of us are stuck with what injection system we got.
If you have tpi you are already in the majority OPINION of what is the best, so be quiet and be happy.
If you have carb. It's been proven to be effective since the 60's so be happy and quiet. Just because you don't know how to reprogram a prom and need a screwdriver don't bitch at people who do.
If you have tbi it is absolutly stupid for most of us to waste $1000+ for a conversion to tpi. It is NOT a magic cure. After the conversion you are out of money and still have bad cam, heads, exhaust.
To go to carb could make it hard to pass emissions . Can we say visual. You still have bad cam, heads, exhaust. Again you have wasted your money and still go slow. Spend your money on other stuff first
So please stop this dumb argument. Your injection system should be one of the last things you worry about on these tbi cars.
At which point you can get a 670 holley off ebay for cheap and slap it one. I actually got mine for FREE! Then learn to burn chips. This is how you make tbi work. Usually it only doesn't run right because the computer is told to make it not run right under certain conditions. You need to make it so the computer doesn't care that suddenly vacum is lower, etc.
There are people on this board that have proved tbi's are fast. Shane Buss, vortecfcar and others.
There are so many other arguments I could go in to, but you guys are dumb.

"Well...uh...well you can't rev to 10 grand" No one's car here is running super moddified class and making power up there so it does't matter.

"But...well..you can't"
So what!

Take care yourself and eachother.

yipeee

 

ONCE AGAIN. KEEP THE GOD-DAMN BS OFF THE BOARDS.

 

Thanks guys for the whole run down on advantages and disadvantages of all 3 systems. I've been trying to figure the best solution for my engine swap and I think I've got it. That is unless a TPI system happens to show up at my front door free of charge. Carb has always been the easiest way to make power but like it's been said before, EFI just has all that advantages other than simplicity. The only problem I see with TBI is the fact that we have these HUGE injectors in the air stream, it's not very effective but seems to be the only logical place for them. I see it as evolution, first we had the carb (wetflow w/no sensors), TBI (wetflow manifold, timing adjusted by sensors not vacuum), TPI (dry flow but batch fire injectors), then the SEFI (sequential meaning injectors fire according to piston position). Nobody here can say that TPI is better then the LS1 injection system. BUT you could all argue at how stupid it is to spend $1000's more for a few extra hp and flatter torque curve. Just like the evolution you get bang for the buck ratios and carb will win because it's been around the longest and still is the most popular. When the carb starts to fade out you will see TBI and TPI parts being more popular and thus prices for those will drop. I know it's been said before I'm sure, but nobody in their right mind could think a carb is superior to TBI or TPI. Okay, done.
Thanks again for the facts. I'm going to be keeping the TBI system with a air gap manifold, adaptor plate, 670cfm TB, 65 injectors, custom chip, and the 330hp vortec crate 350. I think I'll be happy with the drivability and performance.

Cool J. If u ever need help with installtion or questions I would contact Z28Boy@aol.com or try paging him on the boards here. He did the 350HO that ur planning on doing. So far I guess it runs great. He still needs a custom chip and higher gears in the back though. When u gettin that done Brian?

 

i have a 1989 c1500 it has a 350 tbi in it i want to put a carb on it. do you know anything about switching trucks over to carb. if you counld please help me thanks.

 

Have you looked at the dates above? Those guys might not be on here anymore.
Put a carb intake, carb of choice, vacuum advance distributor (hooked to a keyed 12v source), I'd install a fuel pump from a chevy vega (5psi electric intank pump) or get a fuel pressre regulator set to 3-5psi.

 

wow now this thread is interesting. 1992 rs camaro l03.
1. started out tbi. ran ok but could never get the bugs out. the po did all kinds of stuff. removed the tbi system. cut down the harness and went to carb.600cfm holley, edelbrock eps intake, proform hei with all spring and weight kits. installed easily. ok now. set the timing first to 10 degrees. then started going to the carb some. got the dead spot out with a couple a jet changes and a smaller squirter. then went to the dizzy with springs and weights. ended up going from the dizzy to carb. finally got it dialed in at 12* timing at idle. pump the gas and satrted right up. hit it again a few seconds later and then again a few seconds later. we are at idle quick. in town driving was really good. got knock when hot. bumped the timing back to 10* and put one slightly heavier spring in. all good then. always had a split second bog in it off idle when going to wot. but after that hello. now on the freeway it was a better feeling. it picked up faster and would carry the hp better and longer. loved it. then in weather changes and the little idiosynchosies i kept having to tune on the carb with weather changes and all. kinda got tiring. but when i had it running right i thought it was good. kept up with a buddy of mines old tired 350 79 camaro. then got tired of tuning the carb and the dreaded flat spot. so to #2
2. removed and sold the carb set up with everything i had accumulated. bought a tbi system again and started over. ultimate tbi mods with matched injectors. spacer. brand new gm external coil dizzy, accel cap and rotor and msd coil. and a custom tbichips chip and same 180 therm as carb. soldered it all back together a custom way. set timing to 0*. got it all running. was happy. played with the timing and all and i think it was as good as it gets. it runs really well with a smooth idle and good acceleration. great gas mileage as well.
3. tbi before was bad. carb was great for top end and pure power. gas mileage with carb was at 12 to 14 mpg. enjoyed the freeway really well with it. now that i am back to tbi i love it. i did give up the freeway power some but the ideosynchosies is awsome.
4. there will always be those opinions. some will like the carb better cause there are no codes. there are no sensors to have problems and such and it is much simpler. on the other hand i love the sensors and the codes. now i amd happy with it. as for hard 1/4 mile data. no i do not. prolly due to 450 bucks in tires. but i will give an unbiased opinion as i have enjoyed both. simplicity can be veiwed in both directions as well. im a little older and love the ecm age.
5.to say one is better than the other is pure preference. i chose the ecm over carb. it is only my opinion. but i have experienced and enjoyed both. i enjoy my 22 to 23 mpg and a little less power better. but hey to each his own. i commend both. IT IS YOUR CAR.
